Hi my name is Ann, Im new and finding this site so helpful. I have a Canon 7D and few cool lenses. Im not a professional and need help with what I should set my camera to to take some night shots at a High School F.B Game. I was asked to take them for the Team and booster club and I am afraid the shots are going to bomb. My lens I love to use for the day games is the Canon ultrasonic 100-400mm. I also have the 70-200mm but feel I get a bit closer shot with the other. Any suggestions on setting at night/day anything. I need a field trip with an educated photographer but thats not happening. Ive tried asking for help at the local store that specializes in Canon and they were very put out by my questions. Ann
